Chomp Romp is a 4-player minigame found in Mario Party 5. It was also released on the Mario Kart: Double Dash!! bonus disk containing the Mario Party 5 demo, under its original name, Chain Chomp-Walking.
The Chain Chomp is romping through a field of flowers behind the course. The player then blows their whistle, which causes it to break through the fence and onto the course, albeit dazed.
Players attempt to blow a whistle to lure the Chain Chomp to the exit at the end of the obstacle course.
When the player blows the whistle, the Chain Chomp starts moving toward the player until it collides with an object (for instance a swing set). If the player gets hit by the Chain Chomp, the player is stunned for a moment. The first player that gets their Chain Chomp to the end is the winner.
This appears as the second minigame in Mini-Game Decathlon. Here, the player's objective is to get their Chain Chomp to the end as fast as they can to earn as much points as possible, up to a maximum of 1,000. The default record for this minigame in Mini-Game Decathlon is 00:30.00. Also, the minigame ends once all players finish, or 01:30.00 pass.
The player performs their victory animation at the end of the course, with the Chain Chomp right behind them barking happily. There is no ending in the Mini-Game Decathlon variation; the screen fades to white before the results are shown.
